    Carrier QC

    I've seen some mistakes on new units from the factory. Wires landed to the incorrect terminal, txv bulbs strapped to the wrong suction line and so on. We are in the process of installing 3, 10 ton RTUs they are 3phase but run single phase ECM condenser fan motors. The low voltage for the ECMs come off the main board. One of the fans would not run. We found both plugs have Male pins and they were just rammed in. We checked the other two new units and they were wrong also.

    Maybe one of those plugs identifies as a female plug. Even if the "plumbing" is incorrect, who are you to judge?

    Been having issues with Carrier RTU's as well.
    Last one was flat on change ( leak at compressor suction stub ) and another has VFD issues.

    Now that made me laugh out loud.
    I’m surprised the liberals from Berkeley haven’t started protesting molex manufacturers.
    If I do a job in 30 minutes it's because I spent 30 years learning how to do that in 30 minutes. You owe me for the years, not the minutes.

    We just did a job replacing about 27 VAVs all Carrier boxes. What a joke... spade connectors pretty much fall off the terminals. Stickers put on upside down. Garbage stuffed inside the boxes. Electric reheat coils pulled tight in some areas and bunched up and shorted in others. These are made in the US so cant blame Mexico like I can with the RTU. Would be better off buying a generic box.

    Here is a picture of what the pins are supposed to be.

    Years ago worked on a Target change out of about 25 package units & we were starting them up. Everything went well except for one unit would instantly trip ComfortLink alarm. Three good techs couldn't find the fault & was asked to give it a try. Knew the obvious had already thoroughly checked so started chasing every wire per schematic.

    Found load side of compressor A contactor went to comp B.

    B contactor to comp C.

    C contactor to comp A.

    Upon start the CLO current relay would trip. Thought the units were tested before leaving the factory.

    Not that I'm super tech, I'm guilty of getting tunnel vision every once in a while but it's good to have a fresh set of eyes look at an issue sometimes.
    Sorry men, two meme limit.

    male pins on both connectors from the factory. wow reminds me of where I worked as an engineer leading a team of technicians in the 90s. They got an HR employee due to a government requirement for contract bids, and suddenly all PC and sensitivty hell broke loose and they brought in a new supervisor filled with bright ideas but endowed with little technical knowledge and no common sense. This disaster was inserted between our manager and us.

    A total waste because our manager already did almost nothing except sit and stare at his computer all day, hardly even moved because we knew our jobs and did them. They could have hired a couple more techs and increased output and profitability. But no, don't do that, just shoehorn more layers of management into every crevice.

    Anyway the new supervisor was under pressure to document some sort of positive 'sensitivity improvement' and proclaimed that we were to say 'pins and holes' because someone might think 'male and female' connectors were sexist and be offended.

    This was ridiculous and led to "holes" being mispronounced by the technicians, like that long-handled gardening implement. Not going to get into what was joked about when a new design was released using a board with a row of connectors having all the same connector shells to save expense - but they had both pins AND holes, in 5 or 6 different patterns to prevent misconnection of cables.

    4 months later they hired a female tech. The guys quit the joking around out of courtesy, but it didn't take her long to dislike the term "hole" being used to replace the term "female" on general principles and we were asked to go back to the original industry standard terminology after Mr. Supervisor was advised by his boss that the electrical term "receptacle" wasn't a great idea either. The supervisor didn't like the snickering at his expense from both beneath his position and above it.

    That reminded me of a related story.

    While at a Sonic working on an electric fryer, I saw fit to explain to the female manager why I'd need to return another day with parts. I showed her that the male/female connectors for the heating elements were melted down and no longer plug into each other.

    The next day, my supervisor informed me that he'd gotten a phone call from that restaurant manager. She'd specifically requested that I was NOT to be allowed back into her restaurant because, in my conversation with her (yesterday), I had used "SEXUAL INNUENDO" - which she found to be offensive.

    Happened to me and the other guys on a gas install. I was corrected ant told that they were not nipples, but pipe extenders.
    Can someone please explain to me -
    Why is there never enough time to do it right the first time, but plenty of time to do it twice?
